如果您在MySQL中以DATE（或DATETIME）格式存储生日，则可以使用以下查询：

// This week
SELECT * FROM person WHERE WEEK( birthdate ) = WEEK( NOW() )

// This month
SELECT * FROM person WHERE MONTH( birthdate ) = MONTH( NOW() )

// Next month

SELECT * FROM person WHERE MONTH（生日）= MONTH（NOW（））+ 1;

SELECT * FROM person WHERE IF
  ( MONTH( NOW() ) < 12, MONTH( birthdate ) = MONTH( NOW() ) + 1,
  MONTH( birthdate ) = 1)
